雖然聲明與最小和最大python

Question

while True: 
    reply = raw_input("Enter text, (type [stop] to quit): ") 
    print reply.lower() 
    if reply == 'stop': 
     break 
    x = min(reply) 
    y = max(reply) 
    print("Min is " + x) 
    print("Max is " + y) 

我想做一個語句，其中包含一個while語句，它要求一系列的輸入語句，並把它們全部，並找到所有輸入數字的最小值和最大值。任何人都有解決方案？我一直試圖解決這個問題一段時間，但沒有任何運氣。謝謝大家！

Answer 1

這是另一種方法。

while True: 
    reply = raw_input("Enter numbers separated by commas. (type [stop] to quit): ") 
    user_input = reply.split(',') 
    if reply == 'stop': 
     break 
    x = map(float, user_input) 
    y = map(float, user_input) 
    values = (x, y) 
    print("Min is " + str(min(x))) 
    print("Max is " + str(max(y))) 

輸入：

5, 10, 5000

輸出：

Enter numbers separated by commas. (type [stop] to quit): 5, 10, 5000 
Min is 5.0 
Max is 5000.0 
Enter numbers separated by commas. (type [stop] to quit):

縮進在Python中很重要。至於min和max，你可以有兩個變量來跟蹤這些數字，並繼續請求數字直到停止條件。

min = max = userInput = raw_input() 
while userInput != "stop": 
    if int(userInput) < int(min): 
     min = int(userInput) 
    elif int(userInput) > int(max): 
     max = int(userInput) 
    userInput = raw_input() 
    print "Min is "+str(min) 
    print "Max is "+str(max) 

這裏，第一輸入被取爲min和max值。請注意，如果用戶輸入stop作爲第一個值，則min和max也將爲stop。如果你澄清了更多的用戶輸入約束條件會更好。

Answer 3

正如他們所說，你需要保持list的軌道，以獲得min和max。下面的代碼結構：

l = [] 
while True: 
    reply = raw_input("Enter text, (type [stop] to quit): ") 
    print reply.lower() 
    if reply == 'stop': 
     break 
    l.append(int(reply))  #store the values 

x = min(l) 
y = max(l) 
print "Min is ", x 
print "Max is ", y 

IMP：不要忘了int轉換

另一個space conservative方法，你可以嘗試是計算的最小和最大當你輸入。

import sys 
#placeholders 
maximum = -(sys.maxint) - 1  #highest negative value 
minimum = sys.maxint  #highest positive value 

while True: 
    reply = raw_input("Enter text, (type [stop] to quit): ") 
    print reply.lower() 
    if reply == 'stop': 
     break 
    reply=int(reply) 
    if reply<minimum : 
     minimum = reply 
    if reply>maximum : 
     maximum = reply 

print "Min is ", minimum 
print "Max is ", maximum 

Answer 4

你的思路是正確的。你沒有使用min max作爲變量名，這也很棒。如果您使用python 3，請在以下代碼中將輸入關鍵字替換爲raw_input。

希望它的工作！ :)

minn=5000; 
maxx=0; 
while True: 
    reply = input("Enter text, (type [stop] to quit): ") 

    if int(reply) < int(minn): 
     minn = int(reply) 

    if int(reply) > int(maxx): 
     maxx = int(reply) 

    if reply == 'stop': 
     break 
    print("Min is " + str(minn)) 
    print("Max is " + str(maxx))
